The strength and stiffness properties of solid wood or glulam in grain direction are much higher than the strength and stiffness properties perpendicular to the grain direction. Cross-laminated timber (CLT) panels with 90 degree angle inner layers, provide an opportunity for beams loaded in bending and by tensile stresses perpendicular to the grain direction. Due to some disadvantages, the field of application for CLT in beams is strongly reduced. For this reason, a new product, diagonal orientated timber (DLT) with four different ply-angles of 10, 20, 40 and 70 cross layers, was developed and tested in this project. In addition to differing the angles in the layers, a hybrid system of having hardwood (black locust) for outer layers and softwood (eastern white pine) for inner layers, and two alternating cross layers, have been proposed and done in the project to compare the results with the conventional CLT fabrication.
